OpenAI hosts a dev day, TechCrunch reviews the M3 iMac and MacBook Pro, and Bumble gets a new CEO

Hey, folks, and welcome to Week in Review (WiR), TechCrunch’s newsletter covering the past week (or more) of tech industry events. This week marked OpenAI’s first ever dev conference, where the Microsoft-backed AI startup announced several new products. But that is far from the only thing on record.

In this edition of WiR, we highlight Brian’s review of the 16-inch M3 Max MacBook Air and M3 iMac 24-inch; Mozilla’s bet on a decentralized social networking future; Ford shuts down a company that built an app for plumbers, electricians and other trades; and Tim Cook’s thoughts on generative AI. Also on the agenda is WeWork officially filing for bankruptcy, Bumble getting a new CEO, and the spectacular failure of EV startup Arrival.

It’s a lot to get through, as always — so we won’t be late. But first, a reminder to sign up here to receive WiR in your inbox every Saturday if you haven’t already.

OpenAI spends a dev day: OpenAI hosted its first ever developer conference on Monday, and the company had a lot to talk about. Some of the more notable things announced were tools to create custom “GPTs” (ie, domain-specific chatbots), new text-to-speech models, an API for text- to-image model DALL-E 3, and an improved version of OpenAI’s flagship model, GPT-4, called GPT-4 Turbo.

Mac attack: Brian reviews Apple’s new 16-inch M3 Max MacBook Pro and the 24-inch M3 iMac. He sees the iMac as lacking and not necessarily worth upgrading from the 2021 model, except for the M3 chip, which brings “exciting” performance gains to the already powerful M1. As for the M3 Max MacBook Pro, Brian reports that, at $2,500 (plus some expensive add-ons), it successfully splits the difference between the Mac Studio and MacBook Air.

Mozilla is betting on a decentralized future: Sarah spoke with Mozilla’s senior director of content Carolyn O’Hara, who outlined Mozilla’s strategy as it relates to the “fediverse” – a collection of decentralized social networking applications, such as Mastodon, that talk each other through the ActivityPub protocol. The idea, says O’Hara, is to rethink social networking from the ground up.

Ford shuts down SaaS app for field work: Ford has shut down VIIZR, a software-as-a-service company that, with Salesforce, built an app to help tradespeople like plumbers, locksmiths and electricians schedule field appointments, send invoices and manage customers, Kirsten reports. VIIZR, announced in December 2021, is a separate company majority-owned by Ford, with Salesforce as a minority investor.

Apple is betting on generative AI: Apple CEO Tim Cook pushed back against the idea that the company is behind AI in Apple’s Q4 earnings call with investors, as he highlighted the technological advances Apple has made recently. which “would not be possible without AI.” Cook also said that Apple is working on generative AI technologies, lending confidence to reports suggesting that the company is on track to spend $1 billion annually developing generative AI products.

WeWork broke: As predicted, flexible office-space firm WeWork has filed for Chapter 11 bankruptcy protection, listing more than $18.6 billion in debt in a rare collapse for the once high-flying startup founded by Adam Neumann and is bankrolled by SoftBank, BlackRock and Goldman Sachs.

Slack’s loss, Bumble’s win: Dating app Bumble announced a doozy this week: It’s replacing founder CEO Whitney Wolfe Herd with Slack CEO Lidiane Jones. Jones only started as CEO of Slack last year, stepping in for another founding CEO, Stewart Butterfield. Ron and Sarah wrote that — while Bumble now has a clear line of succession — the move leaves Slack in a bit of a pickle.

Arrival failed to deliver: The arrival was set eight years ago to make electric vehicles “more efficient.” Until now, its plan to abandon the gigafactory for local microfactories has proven anything but, writes Harri – thanks to missed production targets, low cash reserves, layoffs and a pivot.
